Abstract: The present disclosure relates to biodegradable and biocompatible elastomeric polymers that are amorphous and have a glass transition temperature below both room temperature and body temperature, and which will homogenously degrade to water soluble by-products with no reported toxicity.
Abstract: The sol-gel templating with the infusion of gas bubbles provides a process for synthesizing polymeric or gel materials while being templated with slow bubbling of various gases into the reacting media upon the polymerization or gelation stage. The process uses a source of gas, which is delivered at a desired rate and pressure via at least one inert tube directly into the reacting solution while the gel is being formed by sol-gel process. The tube(s) have a diameter selected to produce bubbles that result in the desired pore size and the number and placement of the tubes is selected to produce the desired pore structure and surface area in the gel template. The gel may be any gel capable of being formed by sol-gel process. The gas may be selected from carbon dioxide, methane, nitrogen, helium, argon, oxygen, hydrogen, propane, ethane, propylene, ethylene, air, and n-butane and other inert gases.

Abstract: Disclosed is a system for traffic incident reporting comprising the present invention provides a system for traffic incident reporting comprising: a plurality of vehicles and infrastructure units employing a vehicle to vehicle and vehicle to infrastructure communication technology capable of sharing real time and historical information of one or more vehicles involved in the traffic incident and other vehicles in a predefined area of the traffic incident.
Abstract: The reinforced polymer composites from recycled plastic are polymer blends made from recycled polymers that are reinforced with glass fibers and mica. In particular, the reinforced polymer composites are blends of recycled low-density polyethylene (LDPE), high-density polyethylene (HDPE), and polypropylene (PP) with a mica filler that are reinforced with glass fibers, where the low-density polyethylene forms between 30 wt % and 35 wt % of the composite, the high-density polyethylene forms between 15 wt % and 17.5 wt % of the composite, the polypropylene forms between 15 wt % and 17.5 wt % of the composite, the glass fibers form between 15 wt % and 40 wt % of the composite, and the mica forms up to 15 wt % of the structural element. The resultant reinforced polymer composite has a relatively high heat deflection temperature, good mechanical properties (such as increased stiffness and strength), improved thermal stability, and is cost effective to manufacture.

Abstract: The method of synthesizing carbon nanorods (CNRs) and carbon nanowires (CNWs) involves carbonization of a resorcinol-formaldehyde cross-linked precursor gel. The first stage is the synthesis of resorcinol-formaldehyde cross-linked precursor gel. The second stage is carbonization of the gel by heating the gel in a furnace under the flow of nitrogen gas at 500° C. for three hours. The third stage involves activating the carbon by heating the carbon gel in a furnace under the flow of carbon dioxide gas for one hour at 700° C. to form the CNRs and CNWs.

Abstract: Systems and methods are provided for a dynamic user interface for interacting with computer applications by a user physically manipulating interactive floor tiles. The interactive floor tiles may be networked, and may use a communication bus 204 within the network for communicating the connection status of tiles in the network and/or any user input received by one or more tiles in the network. The tile network module may communicate data to a computer via a data collection module. The data collection module may be internal or external to the computer, and may be used to translate data from one communication format to another, for example, from RS485 framework to RS232 framework. The interactive floor tiles may be configured into various shapes at any time by a user, and the changes to the tiles may be mapped to the computer application screen in real-time.

Abstract: Systems and methods for the electrochemical polymerization process for preparation of cross-linked gel. The process includes mixing a hydroxylated benzene and aldehyde in an aqueous media in an inert container to form a hydroxylated benzene and aldehyde mixture. Furthermore, the process includes introducing electrodes into the inert container. Further, the electrochemical polymerization process includes supplying electric current to the hydroxylated benzene and aldehyde mixtures in the inert container through the electrodes. The resultant products of electrochemical polymerization process either gels or activated carbon gels have unique characteristics.
